Abstract
To obtain excellent reception performance while cutting down the amount of computing operation in a MIMO communication system using soft-decision error correction coding. Received waves picked up by receiving antennas 401-1 to 401-R are converted from the radio frequency to the baseband signal by respective receivers 402-1 to 402-R to be output as a received signal. A signal detector 403 calculates bit LLRs of the transmitted signal based on the received signal and the channel-estimated values obtained from a channel estimator 404. The bit LLRs output from signal detector 403 are rearranged by deinterleaver units 405-1 to 405-T in the patterns opposite to the patterns in which interleaving was performed on the transmission side. The bit LLRs after de-interleaving are subjected to an error correction decoding process through decoders 406-1 to 406-T. The bit sequences after decoding are parallel-to-serial converted by a parallel-to-serial converter 407 so that the detected transmission bit sequence is output.
